Offset colours on a layer when exporting with Adobe Media Encoder

[Red83]

Hi everyone,

When I try to export with Adobe Media Encoder, the colours of a layer are completely offset, as you can see in the attached image.
The layer in question is nothing more than a copy of another one that is located at the beginning of the animation, but positioned within a "pre-compose" group.

If, on the other hand, I export with the classic Render Queue, the problem does not occur, the image is perfect.

What could be the cause of this problem?

The first attached image belongs to the beginning of the animation, where the colours are as they should be.
The second image is from the end of the animation, where the colours are completely offset.

In the preview in After Effects, the colours appear perfect throughout the animation.

Without any actual info on your project we can't realyl tell you much, but to me this simply looks like the old gag of not using any real color management on a 32bpc project and the colors going bonkers when encoding to lower bit depths. At the very least you would need to enable the "Use Maximum Quality" option to even come close to correct handling of float colors, but the hard truth is that such projects are unpredictable without genuine CM and you would need to set it up and use it correctly. If none of this applies, then you have to provide much more info.

try to export using software only, maybe it's a GPU problem,

Ok I have just realised that the problem does not seem to be solely related to Adobe Media Encoder.
I just reopened the file and the "offending" layer appears corrupted in colour.

To restore the image to its original condition I have to click on "Reset" in Brightness & Contrast in the Effects applied to the relevant layer and then reapply the same values as before (see file attached)

However, when I go to export with Media Encoder, I still have the same problem (and not with Render Queue).
I just don't understand where this damn problem comes from.

As described before, I used the same layer with the same image and the same effects applied at the beginning of the animation, and everything is fine.
I have also tried copying and pasting the correct layer into the pre-comp where the corrupted one is, but again I get the same result.

I have one more piece of information
I got a series of "logs" once I exported the video...maybe the error is in here.

The file lists a number of items such as

After Effects warning: The file 'C:\Users\pcorp\AppData\Local\Temp\Adobe\After Effects\17.0\Disk Cache - DESKTOP-1II1SJN.noindex\98\9862df4c-f77d-88b5-2a58-afb14cf1976e.ADBE LCV.4 B08062B.AAAAAAAADECQAAgAUAAAAAxAkAAIAFAAAAAAAAAAMQJAACABQAAAAAADECQAAgAUAAA=.aecache' could not be found.

There are several, but I don't understand what it is.

B & C is an hardware accelerated effect, so it once more likely simply comes down to you needing to check the relevant settings in AE and AME as well as updating and fiddling with your graphics driver.

Hi, I have updated my graphics card drivers but the problem is still not solved.

What do you mean by "relevant settings in AE and AME"?

I think the problem stems from AE anyway, as that's where it occurs, so I'd concentrate on fixing the settings in this program at the moment.
